Warnings and precautions for safety Please observe the following safety precautions in order to use safely and correctly the refrigerator and to prevent accident and danger during repair. 1. Be care of an electric shock. Disconnect power cord from wall outlet and wait for more than three minutes before replacing PCB parts.

If the test result is not in this range then it means the inner coil has some problem and the compressor can not work properly. Compressor Protector test —— Use a multi-meter to test the resistance between the two end as the pic show : If there show 000 or almost 0 then it is OK.
Checking the heater If defrost system failure,check the heater and the temperature fuse as well as wires. Measuring temperature fuse and heater resistance about 304Ω then it is OK.( gray and Blue) Checking the defrost fuse Fuse is a high temperature protector of defrost system, when defrosting, if it feel the temperature is more than 73℃, it will cut off the defrost heater, stopping defrost, so that it can protect the parts.
Picture 1 Picture 2 As picture 1,it is the defrost fuse. As picture 2 , using the multimeter measure two foots of fuse, if the value of resistance is 0000, it means normal. Measuring the sensor resistance Rr sensor White line Rv sensor Gray line...
Using a multimeter with the ohm switch to measure the resistor of sensor, normally at surrounding 25℃ the resistor should be about 2kohm and every with the temperature decreases 1℃ the corresponding resistor value would increase about 45ohm. If the measured value is not within the normal scope, the sensor is bad and needs to repair or change.
